Which two devices can cause interference with the operation of a VLAN because they operate on similar frequences?

Devices that can cause interference with the operation of a VLAN include wireless access points and microwave ovens. Wireless access points operate on the same 2.4 GHz and 5 GHz frequencies as many consumer electronics, while microwave ovens can also emit signals in the 2.4 GHz range. This interference can disrupt the signal quality and performance of the VLAN, leading to connectivity issues.
